在我的android项目中，我已成功通过2个字符串[（电视ON（通过按钮1）和电视关闭（通过按钮2）]从我的Android手机到我的电脑通过2个简单的按钮使用WiFi。但在这里我需要使用单个切换按钮[（TV ON（单击切换按钮）和TV OFF（再次单击切换按钮）]而不是2个简单按钮（如上所述）传递2个字符串。 对不起，我的英语不好。 谢谢你。 java代码 -

试试这个..
toggleButton1.setOnCheckedChangeListener(new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if(isChecked){
//do something if on
}else{
//do something if off
}
});
替代
toggleButton1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if((toggleButton1.isChecked()))
{
//do something if on
}
else
{
//do something if off
}
}
});

这是正确的代码
mToggleButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (mToggleButton.isChecked()) {
messsage = "TV ON";
Log.d("On", "Button On" + messsage);
new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
try {
// client = new
// Socket(etIP.getText().toString(), port);
client = new Socket("1.2.3.4", 2000);
printwriter = new PrintWriter(client
.getOutputStream(), true);
printwriter.write(messsage);
printwriter.flush();
printwriter.close();
client.close();
}
catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
} else {
messsage = "TV OFF";
Log.d("off", "Button off " + messsage);// etMsg.getText().toString();
// etMsg.setText("");
// port = Integer.parseInt(etPort.getText().toString());
new Thread(new Runnable() {
public void run() {
// TODO Auto-generated method stub
try {
// client = new
// Socket(etIP.getText().toString(), port);
client = new Socket("1.2.3.4", 2000);
printwriter = new PrintWriter(client
.getOutputStream(), true);
printwriter.write(messsage);
printwriter.flush();
printwriter.close();
client.close();
}
catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
